    I am trying to populate the nozzles in an ink cartridge with ink. The 45 micron holes have tape over the outside of the nozzles and I need to populate all 512 nozzles with ink from the inside.

    I was thinking of creating a vacuum inside the cartridge i.e. taking all of the air out of the cartridge and then releasing ink in. and hoping that these micro holes then replaced the vacuum with ink but I am not sure if this will work due to the surface tension of the ink.

    Does anyone have any ideas how I could do this please?

    Why not take the tape off the nozzle holes and squeeze the cartridge ?

    Because once you take the tape off you will never get it back on as the liquid keeps seeping through, I need to be able to populate the holes without removing the tape.

    change the chemistry of the ink to reduce the energy associated with the interface between the holes and the ink.
